Dimensions of dreaming: A factored scale for rating dream reports.

127 dream reports of 24 Ss were assessed on 20 psychological characteristics. Nearly all characteristics were assessed by 2 raters, and some by S as well, creating a total of 43 variables. These were subjected to principal component analysis and analytic orthogonal rotation. About 63% of the total variance is accounted for by 8 dimensions: vivid fantasy, active control, pleasantness, verbal aggression, physical aggression, heterosexuality, perception (vs. conception), and reference to past experience. In a resulting condensed scale, each dimension is indexed by a single characteristic. These 8 characteristics are essentially uncorrelated. The last 2 are assessed by S alone; rater agreement in assessing the 1st 6 is .63, .71, .62, .74, .44, and .66. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
